When interaction is organized, the sound in all directions is ________.

When interaction is organized, the sound in all directions is ________.

• A. Rayleigh scattering
• B. Specular
• C. Backscatter
• D. Diffuse

Answer: (A)

Rayleigh scattering describes how a wave is scattered by particles much smaller than its wavelength, producing energy in many directions rather than along a single path. When the interaction involves tiny scatterers, the scattered sound becomes nearly isotropic, spreading to all directions and creating a diffuse field. This is why the statement is best filled by Rayleigh scattering: it explains the isotropic distribution of sound that appears in all directions due to the small-scale interactions.
